If you notice that media thumbnails are not displaying correctly, this is the first thing you should check.

In some cases, you may also see browser console errors such as: Uncaught TypeError: Cannot read properties of undefined (reading ‘url’) coming from the admin area.

Check WordPress Thumbnail Settings

In your WordPress admin panel, go to: wp-admin → Settings → Media

WPResidence uses the default WordPress image thumbnails generated through the Media settings.

If these thumbnail sizes are missing, set to zero, or not generated, images will not display correctly in the admin interface.

Your Media settings must follow the default WordPress thumbnail configuration, as shown in the screenshot above.

Setting any of these values to 0 prevents WordPress from generating thumbnails. Add different values than 0.

After changing Media settings, existing images will still be missing thumbnails.

You must regenerate thumbnails for existing uploads.

The easiest way to do this is by using the Force Regenerate Thumbnails plugin from the WordPress plugin repository.
